Abstract (en)

[origin: EP4036469A1] An indicator lamp of the present invention includes a lamp body, a light source unit disposed inside the lamp body, and a light transmissive resin member disposed at a position for transmitting light that is emitted from the light source unit and for outputting the light from the lamp body.The light source unit emits red light having a maximum value of light intensity at a wavelength of 600 nm or longer and 700 nm or shorter. The light transmissive resin member has an L<sup>∗</sup> value of 35 or less, a transmittance of light having a wavelength of 675 nm of 90 % or greater and a total light transmittance of 5 % or greater in the state in which an optical path length of transmitting light is 2 mm. This configuration provides an indicator lamp with excellent design that shows its presence by showing a red chromatic tone when a light source is turned on and that shows a black color tone when the light source is turned off.
